Hi PowerMac Csounders 'round the world,

I have put the last, I hope, 3.47 PPC perf beta release on the Mills
ftp site in:

ftp://mills.edu/ccm/csound.ppc/perf3.47(beta3).bin.hqx.

As usual, you must remove all other perfs from your machine.  The banner
for this perf should read:

MIT Csound 3.47
Mills/PPC 3.4.2b3

That is how you know you are running the right perf.

This release fixes a number of bugs reported from the last beta,
including not wanting to do realtime playback, problems with midictrl,
the inimitable '+' bug, etc.  It also includes all of Perry Cook's
waveguide and physical modelling ugens, mo' betta' pvocing (which is
still being tweaked) and all the other stuff that is in jpff's 3.47
release.  The Piche HTML 3.47 documentation, wherever that is,
should comply with this release.  We are working on bringing our csref
up to 3.47 now.

If you are a user of our port, *please* try to break this *soon* and
get back to me.  This was a major upgrade and involved some pretty
hairy code merges, especially in the MIDI code.  I have tested it with
our "perftests" orc & sco and some files that used to break it, but
that is about it.  I'd be real interested in hearing from you (actually
I'd be real happy *not* to hear from you) if you are using any of the
3.47 things that weren't included in 3.46, *especially* MIDI stuff.

There are still some enhancements to be made, such as guaranteeing
AIF/C Floating Point compliance with a beta SoundHack I've got, the new
csref that Mike is working on, and completely tweaked pvocs.  I hope we
have these things done by next week, at which time we will put out a
NON beta release, so again please try to break this.

We wanted to do a fancy new perf interface, but all that stuff remains
the same, as we decided to concentrate on not crashing your Mac, or
sending perf off into the ozone zone.  The front end remains 3.1b.  We
will wrap it all up together (csound, perf, csref, tests) next week, I
hope.

Dave, for Matt & Mike

I'm experimenting with filtering single pulses with a reson filter with a
very narrow filter band.

with (e.g.) this orchestra:

sr=44100
kr=44100
ksmps=1
nchnls=2


instr 1
a1 linseg 10000, 1/kr, 0, p3-1/kr, 0
a2 reson a1, 621.08, 0.5
a3 reson a1, 207.53, 0.5
outs a2*0.1, a3*0.1
endin

and this score:

i1 0 5

i used to get nice exponentially decaying sinusoids with the old perf.ppc
(v 0.3.2b0).
Now with perf3.47 beta3 i get a very strange-looking distorted sound, that
seems to change when changing p3.
I have tried the same orc/sco with bath's PCCsound also. Result: same
distorted sound. Maybe it's something on the source code?

 i can't quite find a reason for the way GEN19 is implemented, ie DC
offset for each partial. Why not simply a "master" DC offset? Individual
offsets would (maybe) be usefull if they were applied before weighting,
not after... now they just directly cancel each other. 

 so, what am i missing?
